How does Liferay support responsive design?

Liferay supports responsive design primarily by leveraging CSS media queries. Media queries allow developers to apply specific styles based on characteristics of the device being used, such as screen width, height, resolution, and orientation. This means that web pages can adapt their layout and functionality depending on the device type, whether it's a mobile phone, tablet, or desktop.

Using media queries, designers can create fluid layouts that change and adjust to provide an optimal viewing experience across a wide range of devices without the need for altering the HTML structure. This capability is essential for ensuring that content is accessible and visually coherent on various platforms, ultimately enhancing user experience.

In contrast, using image sprites is a technique that can reduce the number of server requests for images but does not inherently support responsive design. JavaScript animations also enhance user experience but do not address responsiveness. Fixed-width layouts can lead to poor usability on devices with varying screen sizes, as they do not adjust to fit the display, which is contrary to the principles of responsive design.
